Once a buyer has done their research, they still always buy products and services for one reason: to solve a problem. They need to be certain. No one makes a buying decision when they are uncertain. When a buyer is uncertain they stall the process.
A salesperson’s goal then is to determine that you have the right product or service to actually solve the buyer’s biggest problem. To do this, you have to get the buyer to trust you enough to talk to you about what they want to accomplish. You must show genuine interest with intention to serve the buyer and not just sell them. Salespeople often get lost in “selling” their product or service. This is a mistake and a waste of everyone’s time.
